Some of the world’s oldest fragments of the Muslim holy text were discovered by the University of Birmingham in July.
Experts think the manuscript, written on sheep or goat skin, dates back to between AD 568 and 645.
Muhammad, said to have received the revelations that form the Koran, lived between AD 570 and 632. But now some historians controversially believe the Birmingham Koran could pre-date Muhammad.
That would contradict most accounts of his life and legacy and may “radically DESTROY the edifice of Islamic tradition”.
Experts say that is the equivalent of discovering a copy of gospel sayings that date back to the infancy of Jesus.
It would contradict beliefs held by the Salafist branch of Islam – whose offshoots include al-Qaeda and ISIS.
